Sephoria 20, the Sephora savings event with discounts for Beauty Insider members, generally goes on sale in July. Rouge members typically get early access first, followed by the sale opening to everyone else.

If you were also asking about the Sephora Savings Event itself in 2025, the spring sale was held from April 4 to April 14, with Rouge members receiving 20% off during early access days (April 4-7), and the sale fully open to all Beauty Insiders from April 8 to April 14. However, the specific event referred to directly as "Sephoria 20" seems to follow a July timeframe.
